' To all whom it may concern:

Be it known thatI, O'r'ro J. GEHRKE, a citizen ofthe United States, residing at Tacoma, in the county of Delaware, State of New York, have invented certain new and useful'ImproveInents in ClICUlZUFSZLW Tables; and I' do hereby declare "the following to be afull, clear, and-exact description .of the invention, such as will enable'others skilled in the art to which it appertains to make and use the same. p 'One object of the present invention is to provide a sawtable structure which will be such as to accommodate pieces of lumber of difierent'diameters or Widths, as well as of difierent lengths;

. a In the construction of the invention for the accommodation of material of considerable length, it is an object to provide, in connection with work supporting portions which are movable to bring work into and out of engagement with the saw, additional work supporting portions disposed to receiveand support material'which may project beyond the table proper, these I supplemental supporting portions being movable to correspond to movement of the material when the latter is operated upon.

It is another object-of the invention to provide means for holding material upon the supporting portions and for-moving the supporting portions to properly position the material with respect to the saw.

Other objects and advantages will be apparent from the following description: In the drawings, Figure 1 is a. side elevation of the completesaw table.

Fig." 2 is a top'plan. "Fig. 3-is a longitudinal section taken on line 33 of Fig. 2.

Fig. 4 is a transverse section takenon line 14 of Fig. 2. i

Fig. 5 is a vertical section taken on line 55 of Fig. 4.

Fig. 6 is an end view.

Fig. 7 is a fragmentary end view showing the work holding carriage moved toward the saw, so that the hinged board is brought into holding engagement with a small piece of work. '1 if Referring particularly to the accompany ing drawings 10 represents a frame on one end of which is mounted a table 11, supports 12 being carried by the table for supporting the shaft 13 of the circular saw l4,which extends transversely of the frame. Extendlng transversely of the frame 10 are the beams 15 on which are securedthe metal strips 16, whereby tracks are formed. A frame including parallel sidemembers 17 extending longitudinally of the frame 10; and the connecting transverse members 18,

is disposedover the frame'10,f and-is provided with the depending brackets 19 in which are mounted the rollers or wheels 20 for rolling engagementon the metal stripsv Disposed of. the before-mentioncd tracks.

transverselybetween 1 the side members of the last-named'f-rame, and j ournaled at their ends in the said side members, are a plurality of .parallel' rollers 21. 'On these 2 rollers the piece of workto be sawed isiplaced and arranged to be easily fed toward the saw. The transverse members 18 extend be-v yond one ofthe side members 1'7, and on one of said extensions. there is mounted a block 23 having an upper downwardly and inwardly inclined face 24:. The adjacent side member '17- hashinged thereto a board 25 which is arranged to rest on the'said inclined face "of the block '23 whereby said board will be held in an inclined position, and limited in its outward swinging movement. Hook-shaped straps 26' are carried by the transverse members 18 and engage with the tracksto hold the frame from movement from said tracks. The side portions of the brackets 19 also depend on opposite sides of the tracks to insure the proper engagementi of the'rollers with the tracks:

At the end of the frame 10," opposite to,

that whichcarr-ies'the saw, are mounteda pair oflbrackets 27 for the removable reception of the hooked ends ofapair of arms 28 carried bya vertical frame 29,"disposed' at that end of the frame 1Q. This frame 29 includes a shaft 30 in the upper portion thereof, which extendsv parallel with the transverse dimension of theframe, and mounted for rotatable as Wellas longitudinal slidable movement; on said shaftis 'a' flanged roller 31 on whichone 'end of' the work'is arranged to rest and slide as said work' is moved toward the saw for cutting and advanced as the saw-cuts through the work?" Mounted on the frame 10, between the table 11 and the adjacent end of the movable frame which supports the work, is a bifur:

cated bracket 32, and pivotally mounted in this bracket is a curved lever 33, the portion which is pivoted to the bracket being provided with an arcuate slot, as at 3A for the reception of the pivot of "said lever. Thus the lever is slidably as well as pivotally connected to the bracket. P'ivotally mounted onthe said lever isa curved hook member 35, the outer end being formed with a point 36 which is adapted to be driven into work disposed upon the rollers 21. This structure is best shown in Fig. 4', from which it will be seen that the outer or handle end of the lever 33 may be manually operated to shiftit'upwardly, which will initially force the point 36 of the dog 35 into work with which it may be engaged, and that further upward movement of the outer end of the lever will move this lever'slidably withrespect-to its point of pivotal mounting. By reason of the arcuate formation of the lever, its sliding movement with respect to its pivot point will shift the dog 35 toward the saw 14, carrying with it the work engaged by the dog, andsince the work is frictionally engaged upon the rollers 21, these rollers and the frame by which they are carried are shifted laterally'upon the frame 10, and the work is brought into engagement with the saw.

hen small pieces of work are being sawed, that is pieces of diameters too small to permit theuse of the lever 33 and the dog 35 the hinged side of the movable table or frame is swung inwardly and pressed downwardly vagainstthework-to hold the work in proper position against'the saw and to prevent slipping'thereof and the movable frame is shifted by pressing against the board. This is clearly shown in Fig. 7.

The roller 31 is particularlyadapted to support the outer end of apiece of work which isof greater length thanthe supporting frame or table, the slidablemovement of the roller permitting it to move with the work as the latter is moved transversely of the saw during the cutting operation. Correspondingly, the rotatable mounting of the roller'31 permits it to revolve as the work is moved'longitudinally for the making of a second out. The flanges oftheroller, of course, retain the work thereon against lateral displacement.

What is claimed is:

1. A work supporting and feeding device for saw tables, including work supporting portions movableto bring work into and out ofengagement with a saw and supplemental work supporting means shiftable correspondingly to the movement of the said 3 for saw tables including a frame, work supporting portions movably mounted upon the frame, and means carried 'by the frame for holding work upon the work supporting portions and for moving such work supporting portions with respect to the frame.

3. A work supporting and feeding device for saw tables, including a frame, a second frame shiftable upon the first frame, work supporting rollers journaled in the second frame, a supplemental frame, and a work supporting roller mounted in the supple mental frame for rotation and for sliding movement. 4

4. A work supporting and feeding device forsawtables, including. a frame, a second frame shiftable upon the 'first frame, work supporting rollers journaled in the second frame, a supplemental frame, a shaft mounted in the supplemental frame and a work supporting roller journaled upon the shaft and slidable longitudinally thereupon.

5. A work supporting and feeding device for saw tables including a frame, a second frame shiftable upon the =first frame, work supporting rollers journaled in the second frame, a supplemental work supporting roller located beyond the second frame at one. end thereof and mounted for sliding movement corresponding to the movement of the second frame upcnthe first frame and means carried bythe first frame for holding work upon the roller and for movement of such work-to shift the second frame.

6. In a work supporting and feeding device for saw tables, the combination with a frame, of a second :frame-sh-iftable upon the first frame, work supporting elements carried by the second frame, a lever slidably and pivotally connectedwith'thefirst frame, and a dogcarried by the lever, said lever being shiftable in its pivotal movement to engage the dog with work disposed upon the work supporting portions, and being shiftable in its sliding movement to move such work and the second frame with respect to the first frame.

In testimony whereof, I affix my signature in the presence of two witnesses.
